The measure of angle ADC in quadrilateral ABCD is; 115°
From the given quadrilateral ABCD, we see that ∠A = 115°
Now, we see that AB is congruent to CD and also AD is congruent to BC.
Since, we have such congruency it means that ∠A = ∠D.
Thus, ∠ADC = 115°
In conclusion, we can say that ∠ADC is 115°
